In this example you can see how easy it is to preserve report pagination after PPR. With a little jquery coding you can attach a function to the pagination request and this way "document" where the pagination goes. After a report refresh you may read those values and paginate back to where you were.

I personally didn't like SQL Developer because of it's clumsy java interface and found TOAD much better. Now, the version 4.0 looks more professional, cleaner and nicer. The new look and feel has been improved a lot. You can now reorder editor tabs without any side effects. SQL Developer has a big advantage if you have to work on a device for which you have no administrative rights - it doesn't require an installation. It is almost perfect if there wouldn't be a funny logic for making it available. On the SQL Developer download page you can choose between several versions:

Only the 64-bit version includes JDK. It is a mystery to me why the other installation versions do not include the same. If your system is a 32-bit only and you have no way to install anything, you will be faced with a problem. The 64-bit jdk will not run there. I helped myself with the following trick:

1. downloaded the jdk 7.0 from here
2. installed it on an another computer
3. copied the entire folder of the installation to the computer where I have no admin rights - jdk1.7.0_45 - and placed it into the SQL Developer folder
4. finally, I changed the sqldeveloper.conf file by changing the line for setting the java home

This new APEX Listener feature is great and I hope they will extend it to the other excel file formats - currently it works for .xls only. If you are using APEX 4.2.3 this will probably not work since there is a bug in that version of APEX.

So, the current limitations are:

1. xls files only
2. APEX 4.2.3 is buggy related to this feature
3. you can upload up to 49 columns since it is using APEX Collection and one column is used for excel tab names during the upload

In addition, you will need to add these four lines of code to the defaults.xml file:
